A method of forming a liquid crystal device, includes: contacting an aqueous solution comprising a surfactant and a receptor molecule with a top surface of a liquid crystal. The liquid crystal is in a holding compartment of a substrate, and the receptor molecule is adsorbed on the top surface of the liquid crystal forming an interface between the liquid crystal and the aqueous solution. The receptor molecule is different than the surfactant. A method of detecting a compound in a flowing stream includes passing an aqueous solution over a top surface of a liquid crystal in a holding compartment of a substrate. The method also includes determining whether a change in the orientation of the liquid crystal occurs as the aqueous solution is passed over the top surface of the liquid crystal. A change in the orientation of the liquid crystal indicates the presence of the compound in the flowing stream.

Detecting interactions at biomimetic interfaces with liquid crystals

The invention relates to a blend of one or more biopolymers with one or more acrylic copolymers, for the purpose of improving the properties of the biopolymer(s). The biopolymer composition comprises 85-99.9 weight percent of biopolymer(s) and 0.1 to 15 weight percent of one or more acrylic copolymers.
